|Title||External and internal heating in the old pulsar PSR B0950+08|
|Author||Dr George Pavlov|
|Description||PSR B0950+08 is a 17 Myr old bright radio pulsar at d=260 pc. X-ray observations of this pulsar provide a rare opportunity to test models of polar cap heating by precipitating magnetospheric particles, while the UV-optical observations can test models of internal heating in neutron stars, which are determined by fundamental properties of matter. The only previous XMM-Newton observation was not deep enough to reliably separate the polar cap and magnetospheric components, while optical observations with ground-based telescopes lacked the needed angular resolution. The proposed deep XMM-Newton observations, supplemented by an HST observation, will be the most detailed multiwavelength study of an old radio pulsar to date.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
